IMPROVEMENT IN LASTS.

Specification forming part of Letters Patent No. 214,114, dated April 8,1879 application filed September 16,1878.

To all whom it may concern:

Be it known that I, GEORGE W. DAY, of Haverhill, in the county of Essexand State of Massachusetts, have invented certain new and usefulImprovements in Boot and Shoe Lasts, of which the following is a full,clear, and exact description.

This invention relates to a last for use in lasting boots and shoes whenthe inner sole on its upper surface is channeled for the stitchesconnecting the inner and outer soles and upper to lie in said channel,and the tacks used in lasting to be clinched or riveted in said channelagainst the last, the lip formed by cutting said channel having beenturned over previous to such lasting and stitching, to be afterwardturned back and secured by cement or otherwise.

This invention consists in a last for boots and shoes, having the middleportion of its bottom recessed, and a rib covered with a strip of metal,said metal strip being set back from the edge of the rib, so as to leavea marginal recess or shoulder extending around the last, the object ofwhich will be fully hereinafter described.

In the drawings, Figure l is a bottom view of a last constructedaccording to this invention. Figs. 2 and 3 are longitudinal and crosssections, respectively, of a last constructed according to thisinvention, with the inner sole attached thereto. Fig. 4 is a face viewof inner sole as channeled and the lip turned over; Fig. 5, a view inmodification.

In the drawings, A represents a last made in accordance with thisinvention; B, the recess, and O the rib or raised portion; D, the innersole of a boot or shoe; E, the channel out in said sole, and F the lip.The rib or raised portion 0 extends around the last A, except at theheel, and is covered on its outer surface, which is the bottom of thelast, with a narrow fiat strip of iron, at.

As shown in the drawings, the recess B follows the outline of the edgeof the last, and it is of a width and depth sufficient for the disposingin it of the lip F of the inner sole, D,when the last A is in the bootfor lasting, &c.

By the lip of the channel cut in the inner sole being disposed in therecess B of the last, the bottom of the rib G, or raised portion of thelast, can and will bear on the surface of channel E of the inner sole,so that the lasting nails or tacks, when driven through the upper andinner soles, will be clinched and riveted against the iron strip on therib of the last, disposing the ends of the nails thus riveted in thechannel E or lower portion, 12, of the inner sole.

After lasting, &c., and when the last is re moved from the boot or shoe,the lip F is then turned over and cemented to its channel portion,making then a smooth and neat finish of the inner sole, and one in whichthe lastingtacks cannot be seen, to disfigure the surface of the innersole or come in contact with the stockings.

The strip of iron 0. is set back a short distance from the outer edge ofthe last, leaving a recess or shoulder, b, extending around the last asfar as the strip of iron extends, so that the solid portion 0 left atthe edge of the inner sole will fit in said recess and around the outeredge of the iron strip, to allow the iron strip to press close to theinner sole in the channel, when a channel is cut in the inner sole, asshown in the drawings.

The iron strip can, however, extend, it desired, to the outer edge ofthe last, as shown in cross-section in Fig. 5; but in that case theinner sole would have to be split from the edge sufficient distance forthe lines of stitches and tacks.

in order to remove the last from the boot or shoe after lasting thesame, the last must be out in two parts, G and H, the line of cutextending from the usual point near the ankle to the extremity, orthereabout, of the toe, as shown in Fig. 3.

To remove the last from the boot or shoe, first take out the part G, andthen the lower part, H, can be raised from its position on the innersole, and be easily taken from the boot or shoe, the reduction inthickness of this lower portion, by this mode of cutting the last,allowing it to be raised, and thus clear the lip F of the inner sole,which lip, if the last were of the full thickness at the toe, wouldprevent 2 llLll l its removal by the strip of iron on the last A lastfor boots and shoes having the mideatehing by its shoulder d on saidlip. dle portion of its bottom recessed and its rib In lieu of iron anymetal could he used for 0 covered with a strip of iron, when said ironthe strip a, as is obvious; and the lust can be I strip is set back fromthe edge, substantially l I made of iron wholly, or other metal, withthe as and for the purpose described.

recess in its bottom. GEO. W. DAY.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-
